Forty years and 40 millions arrest later, some reflections and protests against the policy. In family research, the effects of mass incarceration have gained greater attention in the last 10 years. Because of the concentration of imprisonment by gender, race/ethnicity and age, the family effects are particular to the groups involved. Here’s a graph, then some suggested research:

…the effects of this sea change in the imprisonment rate … have been concentrated among those most likely to form fragile families: poor and minority men with little schooling. Imprisonment diminishes the earnings of adult men, compromises their health, reduces familial resources, and contributes to family breakup. It also adds to the deficits of poor children, thus ensuring that the effects of imprisonment on inequality are transferred intergenerationally. … Because having a parent go to prison is now so common for poor, minority children and so negatively affects them, the authors argue that mass imprisonment may increase future racial and class inequality — and may even lead to more crime in the long term, thereby undoing any benefits of the prison boom. U.S. crime policy has thus, in the name of public safety, produced more vulnerable families and reduced the life chances of their children.

Because most men in jail and prison are fathers, a large number of children may be placed at considerable risk by policies of incarceration. … Both cross-sectional and longitudinal regressions indicate that formerly incarcerated men are less likely to contribute to their families, and those who do contribute provide significantly less. The negative effects of incarceration on fathers’ financial support are due not only to the low earnings of formerly incarcerated men but also to their increased likelihood to live apart from their children. Men contribute far less through child support (formal or informal) than they do when they share their earnings within their household, suggesting that the destabilizing effects of incarceration on family relationships place children at significant economic disadvantage.
